Project description:Tricuspid regurgitation (TR) is an uncommon and underdiagnosed complication of blunt chest trauma. Typical mechanisms include torn chordae, papillary muscle rupture, and radial leaflet tear. We describe an unusual case of traumatic TR due to circumferential avulsion of the anterior tricuspid leaflet from the tricuspid annulus and the crucial role of multimodality imaging in its diagnosis and treatment. (Level of Difficulty: Intermediate.).

Project description:ObjectiveWe investigated the effect of morphological diversity of the tricuspid valve with multiple posterior leaflets on the technical outcomes of tricuspid valve repair.MethodsFrom April 2016 to November 2020, 141 patients were diagnosed with secondary tricuspid regurgitation associated with left heart disease and underwent tricuspid valve repair. We retrospectively analyzed the clinical and echocardiographic data of patients who underwent both preoperative and postoperative transthoracic echocardiography. We divided the patients into two groups according to the surgical technique used to treat tricuspid regurgitation: ring annuloplasty alone (Group 1, n = 109) or additional approximation of leaflet edges (edge-to-edge repair) with ring annuloplasty (Group 2, n = 32). We measured the morphological diversity of the tricuspid valve during the operation in all patients.ResultsThe preoperative tricuspid regurgitation score was higher in Group 2 than in Group 1 (2.1 ± 0.78 vs. 1.6 ± 0.7, respectively; p = 0.0046), and Group 2 contained more patients with two posterior leaflets than Group 1 [20 (63%) vs. 36 (33%), respectively; p = 0.003]. The univariate and multivariate logistic regression analyses showed that the presence of two posterior leaflets was an independent risk factor for additional procedures during tricuspid valve repair (odds ratio, 2.6; 95% confidence interval, 1.1-6.1; p = 0.033).ConclusionsAdditional procedures to reduce tricuspid regurgitation were required more frequently in patients with two posterior leaflets of the tricuspid valve. The morphological diversity of two posterior leaflets is a potential risk factor for a more complicated tricuspid repair.

Project description:BackgroundA mismatch between tricuspid leaflet size and annular dilation is one of the morphological features tied to the development of tricuspid regurgitation (TR).AimsWe assessed the association of the leaflet-to-annulus index (LAI) with residual TR after transcatheter edge-to-edge repair (TEER).MethodsConsecutive patients who underwent TEER for TR were enrolled. Significant residual TR was defined as a post-procedural TR ≥3+, and patients were divided into two groups according to the amount of residual TR. The LAI was retrospectively calculated using procedural transoesophageal echocardiography and was defined as follows: (anterior leaflet length+septal leaflet length)/septolateral tricuspid annulus diameter.ResultsOf 140 patients, 43 patients had residual TR ≥3+ after TEER. The patients with residual TR ≥3+ had a lower LAI compared to those with residual TR <3+ (1.04±0.10 vs 1.13±0.09; p=0.001). In multivariable analysis, the LAI was associated with residual TR ≥3+ (odds ratio [OR] [per 0.1 increase]: 0.57; 95% confidence interval [95% CI]: 0.35-0.94; p=0.02), independent of baseline TR severity or coaptation gap size. Patients with residual TR ≥3+ had a higher incidence of the composite outcome, consisting of all-cause mortality and heart failure hospitalisation within one year after TEER (47.1% vs 26.6%, p=0.02). Residual TR ≥3+ was an independent predictor of the composite outcome within one year (hazard ratio: 2.04; 95% CI: 1.01-4.11; p=0.04).ConclusionsThe leaflet-to-annulus mismatch (i.e., LAI) is associated with residual TR ≥3+ after TEER for TR. A detailed echocardiographic analysis of the tricuspid valve will be conducive to identifing suitable subjects for TEER.

Project description:An 86-year-old patient experienced progressive heart failure symptoms. Echocardiographic evaluation revealed severe tricuspid regurgitation, which was treated by transcatheter edge-to-edge repair. During the procedure, single leaflet device attachment occurred. On the basis of a prohibitive surgical risk, caval valve implantation was performed, with no notable complications. (Level of Difficulty: Advanced.).

Project description:Estimates of the prevalence and importance of significant tricuspid regurgitation (STR) related to implantable device leads are based mainly on case reports, small observational studies, or mixed samples that include defibrillators. We sought to assess whether patients with permanent pacemaker (PPM) leads have an increased risk of STR and to determine mortality associated with PPM-related TR in a large longitudinal single-center cohort. We examined the prevalence of STR (defined as moderate-severe or ?3+) among all echocardiograms performed from 2005 to 2011 excluding those with defibrillators. We then examined mortality risk according to the prevalence of PPM and STR after adjusting for cardiac co-morbidities, left ventricular systolic/diastolic function, and pulmonary artery hypertension. We screened 93,592 echocardiograms (1,245 with PPM) in 58,556 individual patients (634 with PPM). The prevalence of STR was higher in patients after PPM placement (mean age 79 ± 3 years; 54% men) compared with those without a PPM (adjusted odds ratio 2.32; 95% confidence interval [CI] 1.54 to 3.49; p <0.0001). Among patients with a PPM lead, the presence of STR was associated with increased mortality (adjusted hazard ratio 1.40; 95% CI 1.04 to 2.11, p = 0.027, vs no STR). Compared with having neither a PPM lead nor STR, adjusted hazard ratios for death were 2.13 (95% CI 1.93 to 2.34) for STR but no PPM, 1.04 (0.89 to 1.22) for PPM without STR, and 1.55 (1.13 to 2.14) for PPM with STR. In conclusion, in a sample comprising >58,000 individual patients, PPM leads are associated with higher risk of STR after adjustment for left ventricular systolic/diastolic function and pulmonary artery hypertension; similarly to STR from other cardiac pathologies, PPM-related STR is associated with increased mortality.

Project description:AimsTranscatheter tricuspid edge-to-edge repair (T-TEER) has gained widespread use for the treatment of tricuspid regurgitation (TR) in symptomatic patients with high operative risk. Although secondary TR is the most common pathology, some patients exhibit primary or predominantly primary TR. Characterization of patients with these pathologies in the T-TEER context has not been systematically performed.Methods and resultsPatients assigned to T-TEER by the interdisciplinary heart team were consecutively recruited in two European centres over 4 years. Echocardiographic images were evaluated to distinguish between primary and secondary causes of TR. Both groups were compared concerning procedural results. A total of 339 patients were recruited, 13% with primary TR and 87% with secondary TR. Patients with primary TR had a smaller right ventricle (basal diameter 45 vs. 49 mm, P = 0.004), a better right ventricular function (fractional area change 45 vs. 41%, P = 0.001), a smaller right (28 vs. 34 cm2, P = 0.021) and left (52 vs. 67 mL/m2, P = 0.038) atrium, and a better left ventricular ejection fraction (60 vs. 52%, P = 0.005). The severity of TR was similar in primary and secondary TR at baseline (TR vena contracta width pre-interventional 13 ± 4 vs. 14 ± 5 mm, P = 0.19), and T-TEER significantly reduced TR in both groups (TR vena contracta width post-interventional 4 ± 3 vs. 5 ± 5 mm, P = 0.10). These findings remained stable after propensity score matching. Complications were similar between both groups.ConclusionT-TEER confers equally safe and effective reduction of TR in patients with primary and secondary TR.

Project description:BackgroundThe association of postimplant tricuspid regurgitation (TR) and heart failure (HF) hospitalization in patients without HF and preexisting abnormal TR and TR pressure gradient (PG) remain unclear.HypothesisThis study aimed to explore the clinical outcomes of progressive postimplant TR after permanent pacemaker (PPM) implantation.MethodsA total of 1670 patients who underwent a single ventricular or dual-chamber transvenous PPM implantation at our hospital between January 2003 and December 2017 were included in the study. Patients with prior valvular surgery, history of HF, and baseline abnormal TR and TRPG were excluded. Finally, a total of 1075 patients were enrolled in this study. Progressive TR was defined as increased TR grade of ≥2 degrees and TRPG of >30 mmHg after implant.ResultsIn 198 (18.4%) patients (group 1) experienced progressive postimplant TR and elevated TRPG, whereas 877 patients (group 2) did not have progressive postimplant TR. Group 1 had larger change in postimplant TRPG (group 1 vs. group 2; 12.8 ± 9.6 mmHg vs. 1.1 ± 7.6 mmHg; p < .001) than group 2. Group 1 had a higher incidence of HF hospitalization compared to group 2 (13.6% vs. 4.7%; p < .001). Preimplant TRPG (HR: 1.075; 95% confidence interval [CI]: 1.032-1.121; p = .001) was an independent predictor of progressive postimplant TR.ConclusionsAfter a transvenous ventricular-based PPM implantation, 18.4% of patients experienced progressive postimplant TR and elevated TRPG. Higher preimplant TRPG was an independent predictor of progressive postimplant TR.

Project description:Tricuspid regurgitation (TR) is a risk factor for mortality in pulmonary hypertension (PH). TR severity varies among patients with comparable degrees of PH and right ventricular remodeling. The contribution of leaflet adaptation to the pathophysiology of TR has yet to be examined. We hypothesized that tricuspid leaflet area (TLA) is increased in PH, and that the adequacy of this increase relative to right ventricular remodeling determines TR severity.A prospective cohort of 255 patients with PH from pre and postcapillary pathogeneses was assembled from 2 centers. Patients underwent a 3-dimensional echocardiogram focused on the tricuspid apparatus. TLA was measured with the Omni 4D software package. Compared with normal controls, patients with PH had a 2-fold increase in right ventricular volumes, 62% increase in annular area, and 49% increase in TLA. Those with severe TR demonstrated inadequate increase in TLA relative to the closure area, such that the ratio of TLA:closure area <1.78 was highly predictive of severe TR (odds ratio, 68.7; 95% confidence interval, 16.2-292.7). The median vena contracta width was 8.5 mm in the group with small TLA and large closure area as opposed to 4.8 mm in the group with large TLA and large closure area.TLA plays a significant role in determining which patients with PH develop severe functional TR. The ratio of TLA:closure area, reflecting the balance between leaflet adaptation versus annular dilation and tethering forces, is an indicator of TR severity that may identify which patients stand to benefit from leaflet augmentation during tricuspid valve repair.

Project description:BackgroundEndocardial lead in the right ventricle is recognized as a cause for tricuspid regurgitation (TR), but the mechanism remains elusive. We sought to evaluate lead-specific features on the development of TR after endocardial lead implantation.MethodsThis was a prospective single-center study. The patients underwent 2-dimensional echocardiograms before endocardial lead implantation and at follow-up visits at 4 to 6 weeks, 6 months, and 12 months. We assessed the position of the endocardial lead at the tricuspid annulus by 3-dimensional echocardiography, the tricuspid leaflet interference by the endocardial lead by both 2- and 3-dimensional echocardiography, and the degree of lead slack radiologically. Patient characteristics and lead-related factors were evaluated in the prediction of new or worse TR by univariable and multivariable analyses.ResultsNew or increased TR was detected in 38 of 128 patients at the 12-month follow-up. The postero-septal commissure was the most common lead position, and tricuspid leaflet interference detected in 21 patients was associated with a noncommissural lead position. The implantation of an implantable cardioverter defibrillator lead was not associated with new TR compared with the implantation of a pacemaker lead. Tricuspid leaflet interference (P < 0.0001), but not lead position or lead slack, was the only lead-specific factor associated with the development of TR.ConclusionAfter right ventricle endocardial lead implantation, leaflet interference determined by echocardiography, but not the nature of the lead, the lead position at the tricuspid annulus, and the radiological lead slack, predicted TR development at 1 year postimplantation.
